Abstract
Description
Technical Field
[0001] This utility model relates to the field of airborne technology for reducing drag, and in particular to an airborne pod for helicopters with low wind drag. Background Technology
[0002] A pod is typically used by helicopters for aerial lifting operations to carry cargo or equipment, and is connected to the helicopter via slings. The aerodynamic design of the pod is particularly important because it directly affects the helicopter's flight stability, fuel consumption, and lifting efficiency.
[0003] The existing airborne pods only have a streamlined design on the outside to reduce wind resistance. If a strong gust of wind suddenly occurs in the air, the airborne pod will still be subject to significant shaking, which will affect the helicopter's flight path and increase the danger of helicopter operation.
[0004] To address the aforementioned issues, we propose a low-drag airborne pod for helicopters. Utility Model Content
[0005] The purpose of this invention is to solve the problems in the background art by proposing a low-drag airborne pod for helicopters.

The outer side walls of the multiple connecting blocks are fixedly connected to the inner side wall of the drag-reducing frame. A drag-reducing structure is symmetrically arranged on the outer side wall of the drag-reducing frame. The drag-reducing structure includes a guide ramp one and a guide ramp two. Two fixed columns are fixedly connected to the outer side wall of the drag-reducing frame. The guide ramp one is fixedly connected to the left side wall of the fixed column, and the guide ramp two is fixedly connected to the right side wall of the fixed column. Multiple guide wings are fixedly connected to the outer side wall of the drag-reducing frame, and multiple reinforcing rods are fixedly connected to the outer side wall of the fixed column. The multiple reinforcing rods are respectively connected to the inner side walls of the guide ramp one and the guide ramp two.
[0007] In the aforementioned helicopter low-drag airborne pod, the top of the pod is provided with a cover plate, which is connected to the top of the pod by multiple fastening screws. Multiple lifting rods are fixedly connected to the top of the pod, and each of the lifting rods is fixedly connected to a lifting ring.
[0008] In the aforementioned helicopter low-drag airborne pod, two fixing plates are fixedly connected to the outer wall of the drag-reducing frame, and both fixing plates are provided with multiple openings. Multiple guide tail plates are fixedly connected to the outer walls of both guide ramp one and guide ramp two.
[0009] In the aforementioned helicopter low-drag airborne pod, the plurality of connecting blocks are evenly arranged on the outer side wall of the pod body, and the plurality of guide wings are evenly arranged on the outer side of the drag-reducing frame. Both the drag-reducing frame and the pod body are made of high-strength aluminum alloy.
[0010] In the aforementioned helicopter low-drag airborne pod, a plurality of fastening screws are evenly arranged at the four corners of the cover plate, and a plurality of booms are evenly arranged at the four corners of the top of the pod.
[0011] In the aforementioned helicopter low-drag airborne pod, multiple openings are evenly arranged on the outer side of the fixed plate, two fixed plates are arranged on the front and rear side walls of the drag-reducing frame, and multiple guide tail plates are evenly arranged on the outer side of guide ramp one and guide ramp two.
[0012] Compared with existing technologies, the advantages of this low-drag airborne pod for helicopters are: This utility model mainly uses guide ramp 1 and guide ramp 2 on the left and right sides to dissipate the wind force to both sides, which is the main design to reduce the resistance of the entire device. The reinforcing rod can improve the wind resistance of guide ramp 1 and guide ramp 2. If the helicopter turns, the side of the cabin will receive some airflow.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0016] Reference Figures 1-3A low-drag airborne pod for helicopters includes a pod body 1. Multiple connecting blocks 13 are fixedly connected to the outer wall of the pod body 1. A drag-reducing frame 2 is provided on the outer side of the pod body 1. The outer walls of the multiple connecting blocks 13 are all fixedly connected to the inner wall of the drag-reducing frame 2. A drag-reducing structure is symmetrically arranged on the outer wall of the drag-reducing frame 2. The drag-reducing structure includes a first guide ramp 6 and a second guide ramp 7. Two fixed posts 5 are fixedly connected to the outer wall of the drag-reducing frame 2. The first guide ramp 6 is fixedly connected to the left side wall of the fixed post 5, and the second guide ramp 7 is fixedly connected to the right side wall of the fixed post 5. Multiple guide wings 14 are fixedly connected to the outer side wall of the drag-reducing frame 2. Multiple reinforcing rods 8 are fixedly connected to the outer side wall of the fixed column 5. The multiple reinforcing rods 8 are respectively connected to the inner side wall of the first guide ramp 6 and the second guide ramp 7. Two fixing plates 3 are fixedly connected to the outer side wall of the drag-reducing frame 2. Both fixing plates 3 are provided with multiple openings 4. Multiple guide tail wing plates 15 are fixedly connected to the outer side walls of the first guide ramp 6 and the second guide ramp 7. Multiple connecting blocks 13 are evenly arranged on the outer side wall of the compartment 1. Multiple guide wings 14 are evenly arranged on the drag-reducing frame 2. On the outside, both the drag-reducing frame 2 and the cabin body 1 are made of high-strength aluminum alloy. Multiple openings 4 are evenly arranged on the outside of the fixing plate 3. Two fixing plates 3 are arranged on the front and rear side walls of the drag-reducing frame 2. Multiple guide tail plates 15 are evenly arranged on the outside of the guide ramp 1 6 and the guide ramp 2 7. The high-strength aluminum alloy can reduce the weight of the cabin and lighten the burden on the helicopter, while maintaining sufficient structural strength to support the load. The outer walls of the drag-reducing frame 2 are all designed with streamlined arcs to reduce wind resistance. The left and right sides are mainly connected by the guide ramp 1 6 and the guide... The second inclined plate 7 deflects the wind to both sides, which is the main design to reduce the overall resistance of the device. The reinforcing rod 8 can improve the wind resistance of the first guide inclined plate 6 and the second guide inclined plate 7. If the helicopter turns, the side of the cabin 1 will receive some airflow. This airflow will flow quickly through the guide side wing 14 to minimize the impact on the cabin 1. The fixed plate 3 mainly serves a positioning function. Since the outer side of the drag-reducing frame 2 is arc-shaped, it is difficult to judge the position of the entire device without the fixed plate 3. The opening 4 is used to reduce the area of the fixed plate 3 and reduce wind resistance.
[0017] The top of the cabin body 1 is provided with a cover plate 9, which is connected to the top of the cabin body 1 by multiple fastening screws 10. Multiple booms 11 are fixedly connected to the top of the cabin body 1, and each boom 11 is fixedly connected to a lifting ring 12. Multiple fastening screws 10 are evenly arranged at the four corners of the cover plate 9, and multiple booms 11 are evenly arranged at the four corners of the top of the cabin body 1. The helicopter is mainly connected to the cabin body 1 through booms 11 and lifting rings 12. Multiple booms 11 and lifting rings 12 can improve the stability of the connection. Rotating the fastening screws 10 can open the cover plate 9 to see the interior of the cabin body 1.
[0018] To further clarify, the aforementioned fixed connection should be interpreted broadly unless otherwise explicitly specified and limited. For example, it may be welding, gluing, or integral molding, or other conventional methods well known to those skilled in the art.
